我使用光滑的js来获取图像的滑块视图.

这是我的代码.

<div class="slider_wrap add-remove">
    <%= f.fields_for :images do |image_form| %>
      <%#= render 'images_fields', :f => image_form %>
        <div>
          <%= image_tag image_form.object.picture.url,:class=>"drop_down_link even img_prev" %>
        </div>
        <div class="image_upload_div">
          <div class="image-upload">
            <label>
              <i class="fa fa-cloud-upload">
                <%= image_form.file_field :picture ,:'data-role'=>"none",:onchange=>"readURL(this);" , :accept => 'image/jpeg , image/png' %>
              </i>
            </label>
          </div>
        </div>
    <% end %>
    <%= f.link_to_add "Add a picture", :images ,:id=>"add_pic" ,:class=>"js-add-slide", :style=>"display: none;"%>
</div>

<script>
function silder(){
    slideIndex = 0;
      $('.add-remove').slick({
        slidesToShow: 2,
        slidesToScroll: 2
      });
      $('.js-add-slide').on('click', function() {
        $('.add-remove').slick('slickAdd');
      }); …

我的应用程序中有twitter-text gem.

当我进行捆绑安装时,我收到以下错误.

需要在高优先级上解决它.

我也去了github页面https://github.com/twitter/twitter-text/issues/225

但在那里找不到解决方案.

我尝试使用下面的行直接安装,但得到了同样的错误.

gem install idn-ruby -v '0.1.0'

错误

Fetching idn-ruby 0.1.0
Installing idn-ruby 0.1.0 with native extensions
Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

    --with-idn-dir=/path/to/non/standard/location
        or
    --with-idn-lib=/path/to/non/standard/location/lib …

我的功能是:

function collect_que_ids(e) {
  var val = e.val();
  var data_lo = e.attr('data-lo');
  new_hash = {};
  new_hash[val] = data_lo;
  if(e.is(':checked')){
    if(checked_box_hash.includes(new_hash)){
      checked_box_hash;
    }else{
      checked_box_hash.push(new_hash);
    }
  }
  else{
    new_hash_key = Object.keys(new_hash)[0]
    new_hash_value = new_hash[new_hash_key]
    $.each(checked_box_hash, function(key, value){
      if (typeof Object.keys(value) !== 'nil') {
        current_key = Object.keys(value)
        if (current_key[0] == new_hash_key && value[current_key[0]] == new_hash_value) {
          checked_box_hash.splice(key, 1)
        }
      }
    })
  }
};

我在这条线上遇到错误.

if (typeof Object.keys(value) !== 'nil') {

需要解决它.请帮忙.

我用过rails-admin.我在navbar-header栏中输入名称"myappname admin".我想用"myapp"名称更改它.我试图用自定义视图文件更改它

navigation.html.haml

.container-fluid
  .navbar-header
    %button.navbar-toggle.collapsed{ type: 'button', data: { toggle: 'collapse', target: '#secondary-navigation' } }
      %span.sr-only= t('admin.toggle_navigation')
      %span.icon-bar
      %span.icon-bar
      %span.icon-bar
    %a.navbar-brand.pjax{href: dashboard_path}
      / = _get_plugin_name[0] || 'Rails'
      = "myapp"
      / %small= _get_plugin_name[1] || 'Admin'
  .collapse.navbar-collapse#secondary-navigation
    = render partial: 'layouts/rails_admin/secondary_navigation'

但它没有改变我的应用名称.

我想在模式弹出窗口中打开图像/视频，这样我就可以单击一个按钮来显示图像。但是当我同时拥有图像和视频时，如何在 jQuery 中检查这些标签很困难。

我的 html 代码用于在弹出窗口中缩放图像
